SAN DIEGO — The zombies, superheroes, space aliens, pirates and time travelers taking over the streets of downtown San Diego can only mean one thing: Comic-Con is here!
The 44th annual pop-culture extravaganza kicked off Wednesday with preview night, which grants early access to the show floor to attendees with four-day passes.
Lines snaked around both outside and inside the San Diego Convention Center with guests queuing up to collect freebies and have first crack at such limited-edition collectibles as a 2-foot-tall "Transformers" action figure and a Barbie doll depicting Julie Newmar as Catwoman.Photos from the 2013 Comic-Con International Convention in San Diego.
